STANDING-GRAIN THRASHING MECHANISM.

Specification of Letters Patent.

Patented June 6, 1922.

Application filed April 21, 1920. Serial No. 375,457.

Twill whom it may concern: w

Be it known that I, GEORGE SCHAEFER, a citizen of the United States, residing at Russell, in the county of Russell and State of Kansas, have invented a new and Improved Standing-Grain 'lhrashing Mechanism, of which the following is a specification.

This invention relates to the art of thrashing standing grain and an object of the invention is to provide a thrasher for this purpose which is of a simple, efficient and durable construction, combining simplicity, rigidity, ease of operation and cheapness to manufacture.

Another object of the invention is to provide a novel arrangement and combination of parts operating in conjunction with an improved. grain gathering mechanism (formin thesubject matter of my copending a pllcation filed March 15, 1920, Serial 1\o. 365991) to'constitute a machine with capacity and arrangement for successfully handling the air from the blower feeder, which is essential to the successful operation of the stripping cylinder,

A further object of the invention is to provide an arrangement of parts in such' manner that the machine will be as evenly balanced within the'frame as possible. thus ensuring long life and ease of operation,

In its general nature, the invention-resides in thosenovel features of construction, combination and arrangement of parts. all of which will be first fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which:

Fi ure 1 is a side elevation of the .assemb ed machine (the rear portion of the frame carrying the. operators platform and the tiller, etcL, being broken away) depicting the operative position of the motor and stripping cylinder pan (gathering mechanism) with respect to the machine proper. and the almost even balance effected by this arrangement of parts. I

Figure 2 is a rear elevation of the parts of the assembled machine shown in Figure 1.

Figure 3 is a vertical cross section of the machine on the line 3-3 of Figure 4.

Figure 4 is a top plan of the same.

Figure 5 is a vertical cross section taken.

substantially onthe line 5-5 of Figure Figure 6 is a detail vertical longitudinal section taken substantially on the line 6-6 of Figure 4, through the gathering mechanism showing the action of the same. I

Figure 7 is a side elevation of the frame and traction wheels, the harvesting mechanism, motor. etc., being removed.

F gure 8 is a top plan view of the same.

- Figure 9 is a cross section on the'line 99 of Figure 7.,

Figure 1() is a detail top plan view of the motor carrying frame section with the motor and main or first motion shaft in place.

In the drawings, in which like numerals of reference indicate like parts -in all of the figures, 1 iepresents the grain pan of the gathering mechztnism, which mechanism includes the stripping cylinder 2 and the screw conveyer 3for delivering the gathered material to a central position from whence it is discharged into the blower 14. The grain gathering mechanism herein shown and described constitutes the subject matter of my copending application aforesaid and a general description of the same is therefore thought to be sufficient for the purpose of the present application. The gathering mechanism is provided with side frames 4 which carry the bearings for the stripping cylinder drive shaft 5; the latter having apulley 6 over which the drive belt (later referred to) is adapted to pass. The stripping cylinder drive shaft 5 is provided with 'a gear 7 that meshes with an idler gear 8 which is secured'to a sprocket 9 over which a drive chain 1t) passes; the chain 10 also passes over the sprocket 11 of the screw conveyer shaft. The aforesaid parts are mounted on the main angle iron 12 which is carried by the pivoted carrier arms 13. The blower 1-1 which constitutes a part of the gathering mechanism unit, has its shaft 15 mounted in bearings 17 in a special frame 16 and the shaft 15 has a pulley 18 over which adriving belt 19 passesb The motor supporting frame is composed of main frame longitudinal angle irons 20 which are secured to the lower main frame 21 that sustains the wheel bearings 22 for the tract-ionfiyheels 23. upper angle frame which carries the thrashing mechanism proper and. is supported above the lower main frame '21-by the uprights 25 and diagonal braces'26. The motor supporting frame 20 is braced from the lower main frame 21 by the horizontal diagonal braces 27 The tiller pole 28 is con- 24 designates the the solid concaves.

Q a praisers nected' to the frame an 1e irons20 and at its rear end is connecter with the operators by the draft angles 20, andthe first motion shaft 33 is provided with a front drive pulley35 and a rear drive pulley 36 for purposes later explained.

The thrashing cylinder case 37 is sup- 7 ported by standards 38 which are mounted on the-upper angle frame 24 and the cyhnder case 37 is also supported by cross supports 3939--50. The cylinder 40 has its shaft su ported in suitable bearings and it is provi ed with teeth 42 of the usual construction to cooperate with the teeth '41'on' The cylinder shaft 133 is provided with a drivepulley 44 andis driven by a belt 45 from the front drive pulley 35."

46 designates the solid concaves' which carry the teeth 41 and 48 designates the perforated concaves, the concaves'46 and 48 being carried in a concave rest frame 47 which is pivoted at 49 and is adapted to be adjusted through a cam device 51, as shown.

52 designates an extension plate from the end of thesolid concaves to the adjacent wall of the cylinder case soas to prevent "the grain and straw from passing below the case at this point; 53 designates a deflector plate at the entrance to the cylinder case 37 where the duct 54 from the blower 14 communicates with the cylinder cas the duct 54including telescoping sections 55 sustaining aprons. 56, as shown, to allow for the raising and lowering of the gathering mechanism.

59 designates the grain pan whih carries the fishbacks 58, the shoe 57 supporting the separating screens 62. The' gram separating shoe and the grain pan are 'rockably supported by hangers .60 from brackets 61 which are supported on the upper angle.

I a

The blower 66has a shaft "105 with pulle 1 106'andreoeives its-power through belt 10 from a pulley 108 on the blower shaft 77 68 designates the shaker, crank shaft which gives'impetus; through-the pitman 101', 'to

The shaft 77 of the cleaner fan is provided with a sprocket 79' around which a driving chain 81 passes, the chain 81 also passing around 'asprocket on the crank shaft 68. 80

The cleaner fan projects its blast endwiseagainst the separating screens 62 and be-' tween and below the same, as best shown in Figure 5 of the drawings, andthecleaner fan is provided with a suitable'damper 7 8, as shown.

82 represents the grain separating shoe cover in which there is provided a series of upwardly angled deflectors '83, the lower one of which is provided with an apron 84 that extends down into close proximity to the upper separating screen 62 for a purpose presently explained.

At the front of the grain separating shoe cover and adjacent to the thrashing cylinder there is provided a curved deflector or baflie 85 which directs the air stream downwardly and forwardly toward the grain pan 59.

Toward the rear of the rain separating vshoe cover (rear when COIlSldI'GCllIl the dibelt 45 also passing around an idler pulley and belt tightener 89 and around the first motion shaft drive pulley 35. Thus, posi tive motion is imparted from the front main drive: pulley 35 to the cleaner fan shaft and to the thrashing cylinder shaft.

The supporting arm 13 on the left side of the machine is attached at the rear to a specially devised casting 90 which is pivotally mounted on. a second casting 92 providing means whereby the Pan 1 can be raised and lowered for thrashing as the case at hand demands. The swinging casting 90 is arrangedlto carry two small belt pulleys 91 disposed to direct, the driving belt '93 from the. rear' main pulley 36 around the corner of the stripping cylinder pulley 6.
